Dear Experts
Is there open source code to convert losslessly CABAC into CAVLC and vice versa?
ffmpeg can convert CABAC coded H.264/AVC stream to CAVLC one but it does full re-encoding and might impact on quality.
In principle it's possible to convert CABAC to CAVLC and vice versa without re-quantization (although inverse quantization and inverse transform are necessary for reconstructed coefficients, in addition re-deblocking is also necessary).
